newhorsemom, it sounds like your horse was saying 'I am not going to listen to you, I am the boss'. My green gelding does that sometimes. He will be a total butt hole and rebel against me, trying to turn when I don't want him too, actually bucking out towards me. I smacked his hind end with the whip when he bucked.
John Lyons said "never hit a horse the fourth time" well, after the third time he got smacked, he never attempted it again. I always free lunge him, no tack or anything. I don't free lunge before every ride or everything I do. The only times I lunge him, is when he starts getting pushy, and I can tell by place as 'alpha' mare is in a crisis. And don't stop lungeing until he is showing submission. If it has been a good day, I stop and let him come in when he is licking or chewing with his lips. If he was being rude, mean, obnoxiuos and a butt, a wait until his head is lowered and he really means it, that he is submitting to me.
But let me tell you, once that is done, and he does, it is awesome for you to walk with no halter or lead, and the horse will follow you! You can turn to the left, to the right, in a circle, if truly submitted, they will follow you. He acts like the best behaved 10 yr old that is so patient and bombproof after that exercise is done.
**Just let me caution you, when you have a horse behaving dangerous like your mare, make sure your round pen is very big, so if she does act up, or even wants to cut a corner, there is plenty of room for her to do so, and you can still be safe. Sometimes horses spazz out working in too small off a round pen.
